Description
Technical field
The present invention relates to pulling force fatigue experimental device technical field, is specifically that one pulls test unit.
Background technology
For automobile fitting industry, the handle adopted, what lid etc. needed to pull open position pulls reliability requirement higher, this just needs to pull test unit to test test sample, whether requirement is reached by experimental observation current design and the quality of production, the currently used test unit that pulls is drawing machine, drawing machine is provided with the chamber of a fixed measure, chamber put into by tested sample, thus cause test space cannot change according to the tested sample of different size, namely test space has limitation, this point also causes being not easy to staff's viewing test real-time condition, in addition, because drawing machine is when pulling, larger change can be there is in the pulling force that its wire drawing applies with the angle pulling open position, so the stability of described angle cannot be ensured, thus the pulling force causing wire drawing to apply is not close to actual situation about using, make test not accurate enough.
Summary of the invention
The technical problem to be solved in the present invention is, provides that a kind of test space limitation is little, larger change can not occur for the pulling force that applies and the angle pulling open position pulls test unit, and then convenient test, obtains test findings comparatively accurately.
Technical scheme of the present invention is, the present invention pulls test unit, it comprises control module, servomotor, variator, transmission shaft, turbine and worm, swing arm, for driving the rotating shaft swung in swing arm surface level, force snesor, wire drawing or pull bar, the shaft of servomotor is connected with transmission input, transmission output is connected with transmission shaft one end, worm screw is located at the transmission shaft other end, rotating shaft one end is located at by turbine, the rotating shaft other end is connected with swing arm one end and swings to drive in swing arm surface level, force snesor and the swing arm other end are rotatably connected force snesor can be swung in surface level, one end of wire drawing or pull bar is connected with force snesor, the other end of wire drawing or pull bar is used for connecting by subjects, servomotor, force snesor are electrically connected with control module respectively.
Principle of work of the present invention is, first workman will be fixed by subjects (such as using frock clamp), then by the other end of wire drawing or pull bar with pulled open position by the need of subjects and be connected, in connection procedure, again wire drawing or pull bar are fixed on after the angle adjusted wire drawing or pull bar and need pull open position and need pull open on position, described angle can set as required, then control module controls servomotor rotating, servomotor rotating can finally drive rotating shaft rotating, rotating shaft rotating can drive swing arm reciprocally swinging in surface level, reciprocally swinging drive sensor surface level in the reciprocally swinging of swing arm in surface level, force snesor reciprocally swinging in surface level drives wire drawing or pull bar reciprocal telescopic, wire drawing or pull bar reciprocal telescopic just can repeat to open, closedown need pull open the action at position to simulate actual using state, because force snesor and the swing arm other end are rotatably connected to make force snesor can swing in surface level, so described angle is being opened, closedown need be pulled open in the action at position and change hardly, technical scheme of the present invention adopts servomotor to export adjustable force and controlled speed, rack-and-pinion auxiliary driving is used again by reducing gear, finally control to pull open power and the speed of being pulled open position (such as handle) by the need of subjects, and by force snesor and the velocity measuring to servomotor, sampling analysis, through the required Various types of data of control module display and result.
After adopting said structure, the present invention compared with prior art, have the following advantages: in conjunction with technique scheme and principle of work known, the mutual cooperation of each parts can repeat to open, closedown need pull open the action at position to simulate actual using state, owing to there is not the structure of chamber, so test space is spacious, limitation is little, when needs are tested in constant-temperature constant-humidity environment, only need the turbine and worm being positioned at the transmission shaft other end, swing arm, for driving the rotating shaft swung in swing arm surface level, force snesor, wire drawing or pull bar are placed in spacious climatic chamber (this kind of climatic chamber, testing crew can be held enter with viewing test real-time condition), because force snesor and the swing arm other end are rotatably connected to make force snesor can swing in surface level, so described angle is being opened, closedown need be pulled open in the action at position and change hardly, comprehensively above-mentioned, it is little that the present invention has test space limitation, the advantage of larger change can not be there is in the pulling force applied with the angle pulling open position, and then convenient test, obtain test findings comparatively accurately.
As improvement, it also comprises counterweight, fixed pulley and bracing wire, bracing wire one end is connected with counterweight, for connecting by subjects to provide a pretension to position need be pulled open by subjects after the bracing wire other end walks around fixed pulley, pilot project has been enriched in arranging like this, makes function of the present invention more powerful.
As improvement, control module is industrial control system, because industrial control system control is accurate, processing power is stronger, adopt industrial control system, configuration software, multi-channel data acquisition module, realize the sampling processing to the speed in process of the test, power, time etc., and realize all kinds of results, data preservation, data analysis judgement etc. needed for test by system software, be more conducive to the raising of performance of the present invention.
